The superior tensile strength is favoured for applications where the joint is subjected to very high service loads. A9 bolts were developed to be compatible with the requirements of crawler equipment manufacturers such as Caterpillar, Komatsu and John Deere, but the range has found to be suitable in a variety of applications that need high clamping force.
Carefully controlled manufacturing and quality procedures result in bolts that are capable of delivering all of the following benefits:
Extra strength: 180,000 lbf/in2 is 20% higher than SAE J 429 Grade 8
Increased head height: improves the wrenching surface during tensioning
Rounded thread roots: reduces the possibility of fatigue failure.
